1. Elytraria crenata, Vahl. De Wildeman and Durand have 
described (Comptes-rendus Soc. Bot. Belg. xxxviii. 42), under the name 
Tubiplora paucisquamosa, an Elytraria which was sent to them by 
Dewévre from Bania Lecoula, in the Upper Congo region, and by Calva 
from Gandayanga, in the Lower Congo region, which from their descrip- 
tion seems to be the form of Z. crenata named on p. 28, as distri- 
buted through the Great Western forest region from Lagos to the 
Gaboon River and eastwards to Niamniam Land. It does not appear 
to be #. marginata, Vahl, but is the #. marginata of Beauvois, of 
Nees, and of Hooker (ll. cc.). Lindau (1. ¢.) applies the name 7ui- 
Jlora syuamosa to it; but then he unites it and the common South 
American species, to which Jacquin’s name, Verbena squamosa (Hort. 
Schoenb. i. 3, t. 5), obviously belongs. 
la. Hygrophila lindaviana, Burkill. Herb 20 in. high, more 
or less hirsute. Stems quadrangular. Leaves of the main stem sessile, 
lanceolate, auricled at the base, attenuate and acute at the apex, 3-7 in. 
long, }-1 in. broad, the auricles 5 lin. long; smaller leaves stalked. 
Flowers white or pale purple, in dense clusters in the axils of the leaves, 
with thorns as in /7. spinosa, which, however, are so short 2s to be 
hidden by the bracts and calyces; bracts and bracteoles lanceolate, 
acuminate, ciliate-hispid; spines $ in. long. Calyx with the upper 
sepal 1 in. long, the others shorter; the lower pair fused almost to the 
tips. Corolla-tube about 1 in. long. Stamens unequal, with the fila- 
ments of the lower pair broadened, each attached to the filament cf the 
upper stamen of its side at the base. Capsule 4 in. long, 8-10-seeded, 
elliptic-lanceolate.—Asteracantha lindaviana, De Wild. & Durand in 
Comptes-rendus Soc. Bot. Belg. xxxviii. 100, and Plant. Thonner. Congol..

South Central. Congo Free State: Evamkoyo; near Businga, Thonner. 
Very closely allied to H. spinosa, T. Anders., if truly distinct. The authors call} 
attention to the unusual number of stopples (viz. four) which they observed in the 
pollen. They describe the pollen as having about 20 lines running from pole to pole, 
and state that the pollen of H. spinosa differs in having fewer ; but this is not 
always the case. 
16a. Hygrophila rhodesiana, S. Mocre in Journ. Bot. 1900, 201. 
A low plant, springing up after being cropped down, Old stems quad- 
rangular, scarcely 1 lin, in diam., erect, glabrous. Leav “ near, con- 
spicuously ciliate with white hairs, upwards of $ in. long: 2 i prea , 
acute, the midrib prominent below. Spikes very few-flowere , or 2 
flowers at each node; bracts like the leaves. Flowers conspicuous, purple. 
Calyx-lobes linear-subulate, ciliate, divided almost to the base, unequal, 
the longest 4 in. long, the others 5 lin. long, almost setacoous fe be 
tip. Corolla-tube as long as the calyx-lobes, suddenly widened into. 
the throat; lower lobes 14 lin. long an 
d almost 2 lin. broad, upper 
smaller. Stamens in two pairs, the filaments of those of each side-
